Maybe Common Tasks in the Development Manual? Something like this: Changing the hostname === By default the configured hostname in an image is the same as the machine name, i.e. qemux86. This can be changed by altering the value of the variable "hostname" in the base-files recipe, with either a bbappend (hostname="myhostname") or configuration file (hostname_pn-base-files = "myhostname"). If the hostname is unset then the image will have no default hostname in the filesystem, making it suitable for environments with dynamic hostnames such as virtual machines. 49273 1 srifenbark 2015-03-06 19:10:55 +0000 Ross, I don't get this. You say that by default, the configured hostname in an image is the same as the machine name. Then, you say you can alter that by setting "hostname" in the recipe or messing with the configuration file. But if the hostname variable is unset then the image has no default hostname in the filesystem? There are terms here I must not understand or assumptions being made in the text because it seems contradictary.

You can change the variable to any other value (I use hostname_pn-base-files="bob" so all my images are called bob for ease of testing), or set it to "" and no hostname will be written into the image. When I say written into the image, I mean written to /etc/hostname. Hopefully that helps? 49499 4 srifenbark 2015-03-17 17:15:22 +0000 Ross, I have a section in the YP Development Manual called "Customizing Images" (http://www.yoctoproject.org/docs/1.8/dev-manual/dev-manual.html#usingpoky-extend-customimage). That section has a bunch of sub-sections. How about creating a new subsection that specifically addresses how to change the hostname written into etc/hostname of the image? To me, this is customization of sorts. We could use your specific debug example as rationale for doing this. Would this work? Scott 49525 5 ross.burton 2015-03-18 09:27:48 +0000 Yes, that sounds good. 49549 6 srifenbark 2015-03-18 15:34:38 +0000 Ross, Please look over the new section at http://www.yoctoproject.org/docs/1.8/dev-manual/dev-manual.html#usingpoky-extend-customimage-image-name. I need to know if "base-files" in that sample command is a placeholder and not a literal. If it is a placeholder then I need to change the formatting. Thanks, Scott 49614 7 ross.burton 2015-03-20 20:54:33 +0000 First, base-files is a literal so the formatting is correct as far as I can tell. The final paragraph implies the wrong facts: "Another point of interest is that if you leave the variable "hostname" unset, the image will have no default hostname in the filesystem. This condition is suitable for environments that use dynamic hostnames such as virtual machines." You can't leave hostname unset as it has a default value. You can unset it by assigning "", as the note already mentions. Maybe remove the note and change the paragraph to say "unset the variable with =''"? 49615 8 srifenbark 2015-03-20 22:28:10 +0000 Ross, I made some changes. Please verify that they are okay. Once you do that I can close the bug. See http://www.yoctoproject.org/docs/1.8/dev-manual/dev-manual.html#usingpoky-extend-customimage-image-name. Thanks, Scott 49616 9 ross.burton 2015-03-20 23:24:57 +0000 Looks good, closing. Thanks Scott!
